HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 402,153, dated April30, 1889.

Application filed February 4, 1889. $eria1No.2-98,545. (N0 model.)

person skilled in the art or science to which said invention appertainsto make and use the same, reference being had to the accompanyingdrawings, forming part of this specification, in which- Figure 1 is asectional view representing my improved device in use in a building;Fig. 2, an enlarged sectional view showing the lower funnel of the drumor heater, the

sliding pipe being shown in side elevation and withdrawn from thechimney; Fig. 3, a

Like letters of reference indicate corresponding parts in the differentfigures of the drawings.

My invention relates especially to means for utilizing the hot air andproducts of combustion which ordinarily escape through the chimney of abuilding for heating purposes; and it consists in certain novelfeatures, as hereinafter fully set forth and claimed, the object beingto produce a cheaper, simpler, and more effective device of thischaracter than is now in ordinary use.

The nature and operation of the improve ment will be readily understoodby all con- Versant with such matters from the following explanation.

In the drawii1gs,A represents the chimney of a building, and B a stovesituated in one of the lower rooms thereof. A funnel, 0,.of the stoveopens into the chimney in the usual manner. A metallic drum, D, isdisposed in a room above that containing the stove B, and is connectedwith the chimney A by two funnels, E G, leading, respectively, from theupper and lower part thereof. A pipe, II, is fitted to slidelongitudinally in the funnel E,

the outer end of said pipe being provided with a vertical plate, I),which closes said funnel when the pipe is withdrawn from the chimney, asin Figs. 2 and 5.

The pipe H is provided with a mouth or opening, d, on its lower side ofa length equal to the width of the interior of the chimney A. Avertically arranged rod, f, is fitted to rotate in the pipe II by meansof an annular flange, g, on its lower end, (see Figs. 3 and 6,) whichworks in a socket, h, within said pipe. The rod f projectsupward throughthe top of the pipe and a longitudinal slot, 1', in the funnel E, beingprovided on its outer end with a thumb-piece, 76-. Ahorizontally-arranged bar, 7., (see Figs. 4 and 6,) is secured centrallyon the rod f, and is provided at each end with a downwardly-projectingarm, on. A horizontally-arranged flat bar, 19, is pivoted at q on eachside of the pipe H, at the inner end thereof, said bars being adapted tobe moved or swung laterally in said pipe. .One bar is provided with alongitudinal slot, 0'', situated in front of the vertical rod f, and theopposite bar 19 with a circular slot, 0', disposed at the rear of saidrod, (see Figs. at and 5,) the arms m of the bar Z respectively work ingin said slots. 011 the rear or free end of each flat bar 19 is secured ahorizontally-an ranged outwardly-projecting head or plate, 1, adapted tobe projected laterally through the mouth (I of the pipe, and of suchsize that they will completely block the chimney A at either side ofsaid pipe when so projected.

In the use of my improvement, the drum D being disposed in a room of thebuilding, 'as described, if it is desired to utilize the heat escapingfrom the stove B, the pipe H is pushed out from the funnel E by means ofthe bar f, which slides in the slot t' in said funnel, until said pipeprojects into chimney, as shown in Fig. 1. The flat bars 1) being in theposition shown in Fig. 5, by turning the thumb-piece 7c and revolvingthe rod f from right to left the arms m of the bar I, secured thereto,move in opposite directions in the slots 4, thereby forcing said pivotedflat bars apart and projecting their heads tlaterally through the mouthof the .pipe, as shown in Fig. 4:. This practically blocks the chimneyA, and directs the heated air, smoke, &c., from the stove through saidpipe and funnel E into the drum. D, whence it passes back into thechimney through the funnel G, as inch-- cated by the arrows in Fig. l.The drum and its funnels expose a large surface within the room, fromwhich the heat is radiated in a manner readily understood without a moreexplicit description. To open the chimney again the rod f is revolvedfrom left to right, moving the fiat bars toward each other andWithdrawing the plates t within the pipe H. Said pipe is then moved backinto the funnel E, the mouth of which is closed by the plate I),preventing the smoke from entering the drum, as shown in Fig. 5.

Having thus explained my invention, What I claim is- 1. In a heatingapparatus, the combination of a drum provided with an upper and lowerfunnel opening in to the chimney, a pipe fitted to slide in the lowerfunnel and be projected into the chimney, and pivoted bars in said pipehaving head-plates adapted to be proj ected into the chimney, wherebythe heated air in said chimney may be directed into said drum,substantially as described.

2. In a heating apparatus, the combination of a drum-provided withfunnels opening into the chimney, a sliding pipe in one funnel adaptedto be projected into the chimney'and provided with a mouth, pivoted barsin said pipe provided with horizontal head-plates, and a rotating rod insaid pipe having arms working in slots in said bars, whereby they may bemoved to project their heads laterally into said chimney, substantiallyas and for the purpose set forth.

3. In a heating apparatus, the combination of a drum provided withfunnels opening into a chimney, a pipe fitted to slide in one funnel andbe projected into said chimney, a mouth in said pipe, two bars pivotedwithin the pipe and provided with head-plates adapted to be projectedlaterally through said mouth, a rotating rod in said pipe, and a bar onsaid rod provided With arms working in said pivoted bars, whereby theymay be actuated as said rod is revolved, substantially as described.

4. In a heating apparatus, the combination of the drum D, provided withthe funnels E G, the pipe H, fitted to slide in the funnel E, andprovided with the mouth 01, the bars 1), pivoted in said pipe andprovided with heads t, and means, substantially as described, foractuating said bars to project their heads through the mouth of saidpipe.

5. In a heating apparatus, the combination of the drum D, provided withthe tunnels E G, the pipe H, fitted to slide in the funnel E and havingthe mouth at and plate I), the bars 1), pivoted in said pipe andprovided with the heads t, the rod f, fitted to rotate in said pipe andprojecting through the funnel-slot i, and the bar Z on said rod providedwith the arms m, Working in slots 9 in said pivoted bars, all beingarranged to operate substantially as described. I

6. In a device of the character described, a tube fitted to slide in adrum-funnel and be projected into a chimney, said tube being providedwith pivoted bars having head-plates adapted to be projected through themouth of the tube and block the chimney, whereby the heated air arisingtherein may be directed into said drum, substantially as described.
